Hey eduardo,

We'll first, I would suggest you be very careful when you graduate and attempt to get a job in the US. Once, you get an H1 visa, its illegal for you to work for anyone other than the company that applied for your H1

As for non-resident aliens. There's pretty much nothing but bad news there because you dont get a standard deduction unless your Indian. The only benefit is if you're working for a company that is related to your education, then you dont need to pay social security tax.

Other than that, I cant really think of much else you have to watch out for off the top of me head generally.
